The 2N6768 PDF, 145 KB, appears in the schematic index but its title is purely a JEDEC discrete component code. It gives no model, brand or board number.

PDF datasheet for the 2N3393, 296 KB, placed in the schematic category. The same size appears for the 2N3390, 2N3391A and 2N3392 entries, which points to one combined…

Firmware dump named g500lenovo, which points to a Lenovo G500 notebook, though no board number or revision appears in the name.

ZIP archive, 556 KB, titled M2N68-AM, matching a desktop motherboard model name. No revision or content type appears in the name, so inspect the files after unpacking.

PDF of 1.44 MB named HT7166, catalogued under schematics, with no device, brand or board stated in the name.

Document numbered UM10155, a 179 KB PDF. The UM prefix is used by NXP for user manuals, but the name does not reveal which product it describes, so open it to identify…

ASUS K42N firmware with no file extension, 2 MB in size, which suits a 16 Mbit SPI flash chip. No revision or status appears in the name.

Archive labelled only Quanta ZRL, a 1.24 MB RAR with no laptop brand, revision or file type in the name. ZRL appears to be a Quanta project code.

Small 330 KB RAR archive named for BoardViewR4 with a BRD reference, apparently a boardview viewer build or related tool for BRD-format files.

BIOS archive of 2.48 MB for Inventec board 6050A2503201-MB-A02, revision A02. No laptop model or firmware version appears in the name.

Samsung BN44-00520C power board schematic, a compact 176 KB PDF, revision C per the name.

Datasheet for the LTC4412HV from Linear Technology, a low-loss PowerPath controller that drives an external P-channel MOSFET as an ideal diode.

BIOS firmware archive labelled for the Dell Inspiron 14 7440 2-in-1, tied to board number 233058-1, which follows the Wistron numbering pattern.

Firmware package for the ASUS TUF FX516PC gaming laptop, mainboard revision 6.0, stored as a rar of roughly 9.6 MB.

Datasheet PDF of 64.4 KB for the HA17324, a quad operational amplifier from Hitachi following the familiar 324 layout.

PDF of about 179 KB for the 2SD2531, filed as a schematic but probably the component datasheet.

A 107 KB PDF titled with the lowercase part number 2sd1565, catalogued as a schematic yet almost certainly a transistor datasheet.

The name pairs the 2SK2078 with STW9NA80, an STMicroelectronics-style part number, so this 133 KB PDF may cover both devices or present one as an equivalent.

A 109 KB PDF for the 2SK1439, filed with schematics but most likely the manufacturer's data sheet for this transistor. The JIS 2SK prefix denotes an N-channel FET.

PDF for the 2SK1238, a Japanese 2SK-series N-channel MOSFET, size 45.9 KB. No manufacturer, package or revision appears in the file name, so match the printed marking on…

A 294 KB PDF for the 2SK209, filed as a schematic. In JIS semiconductor nomenclature the 2SK series is N-channel FETs, so this is effectively a component datasheet.

The 2SJ349 P-channel FET is described in a 418 KB PDF, catalogued under schematics though it is a component datasheet.

The 2SJ305 is described in this 335 KB PDF, listed among schematics. No board number or brand appears in the name.

Reference PDF for the 2SD1197 transistor, 134 KB in size and indexed as a schematic, though the file name is only a part number and reads as a datasheet.

Transistor reference for the 2SC5262, delivered as a 126 KB PDF and catalogued as a schematic.

The 2SC4685 is documented in this 186 KB PDF, filed as a schematic though the name is a transistor part number.

Transistor documentation for the 2SC4678 in a 220 KB PDF file, sorted into the schematic category.

This 28.6 KB PDF carries the part number 2SC4635LS, apparently a package or lead-form variant of the 2SC4635 NPN transistor.

Datasheet candidate for the 2SC4455 transistor, a 100 KB PDF although filed with schematics.

Named after transistor 2SC4452, this 98.8 KB PDF is listed as a schematic but most likely contains the component datasheet.
